This indicates that the R12KSA01 host on port 42029 was not accessible, so nobody can use it.

Recommended Action

There are two possible reasons why this happens: The Driver parameters in a DEF file are missing the DataStore host name and port number (where it listens). Configure these using the following Driver parameters: Driver:DataServerPort = "42029", Driver:DataServerName = "R12KSA01" CDS is not installed and running.

Possibly the old CDS installation did not require it to be running and any
first time connection would start CDS for the rest of the users. With a socket
CDS installation, it must be running prior to any user trying to establish a
connection. Also, every CDS user needs to verify if a connection is alive and
if not it is not, it must be reconnected on every transfer attempt if they need
to retrieve data from CDS. This data displays during a
connection attempt.The following might happen in a log:

This indicates that the connection is maintained automatically whenever CDS starts.

Verify CDS status by doing the following:
Check if Cisco Data Store was installed on R12KSA01 and the default port was chosen as 42029 by checking the Registry
on the R21KSA01 machine: HKLM\Software\CiscoSystems\ObjectStoreserverSocket\Conections "ListenPort"=42029 (in decimal)Start
Cisco Service Control (via Program Files) on R12KSA01.

An entry for a newly installed Cisco Data Store displays; select it and click the Start button. The
cmd window should display and indicate that Cisco Data Store is running and listening on port 42029. Do the following: If the connection to CDS is unavailable from a client machine, try pinging the CDS machine. Verify the machine where the driver is
installed (Siebel Comm Server). If you do not have the CDS installed, see Chapter 2, “Installation,” of Cisco Unified CRM
Connector for Siebel for installation instructions. After performing these steps, do the transfer again and check if the connection to CDS is re-established and bookmark it.
